Main Point:

Our Solar System has ninth planet in the outer spaces as evidenced by researchers.

The Astronomical Journal

Study Further:

Researchers have recently reported that they have found the best known evidence for the existence of ninth planet, referred to as Planet X or Planet Nine, at the outer limits of our Solar System. However, it has been noted that there are no direct evidences for the presence of ninth planet. Researchers have based their argument about the existence of ninth planet on mathematical models and computer simulations made from six Kuiper Belt objects, which are found to be affected by the presence of some large thing.

“Recent analyses have shown that distant orbits within the scattered disk population of the Kuiper Belt exhibit an unexpected clustering in their respective arguments of perihelion… We find that the observed orbital alignment can be maintained by a distant eccentric planet with mass  10 m whose orbit lies in approximately the same plane as those of the distant KBOs (Kuiper Belt objects),” researchers wrote in the paper.

That planet is approximately equal to the size of Neptune. It has a mass of about 10 times that of Earth. Due to its huge mass, it is considered as a planet without any doubt. It revolves approximately 20 times farther from the sun as compared to Neptune. It has been reported that it was hidden from researchers due to highly elliptical path, taking about 10,000-20,000 years to complete one circle at a very far off distance from the Sun.

“All those people who are mad that Pluto is no longer a planet can be thrilled to know that there is a real planet out there still to be found,” Mike Brown, the Richard and Barbara Rosenberg Professor of Planetary Astronomy says. “Now we can go and find this planet and make the solar system have nine planets once again.”
